UPDATE: The new details are bizarre, and involve Jay Penske urinating on a woman:

According to a police report, the incident was initially reported as an assault and battery when two women approached police on Broad Street, claiming they had been assaulted by two men, later identified as the Penske brothers, at the yacht club's parking lot.

One of the women claimed the Penske brothers were urinating in the parking lot, and that when she confronted Jay Penske, he "turned and continued to urinate on her boots. He then proceeded to grab her arm and push her. (The woman) also states that Mark before he ran away pushed her and they both then ran to the house on Yacht Club property."

Police claimed they apprehended Jay Penske attempting to run away from the club, and that they found Mark Penske at the employee apartment after he had fallen down the staircase, suffering several cuts on this right arm.
